BJP also waded into the war of words supporting Team Anna's demand for a probe into the allegations of corruption against the UPA government, saying it is natural that the "taint" reaches Singh though he is honest as he is the leader.

"PMO clears Prime Minister. Did Dhritarashtra in Mahabharata not support Kauravas even after they attempted to disrobe Draupadi? Indian genes/culture? Or?," Bedi tweeted.

She said Team Anna is focussed on the party in power at the Centre because it alone can give an effective central law not opposition.

"Do or Die fast from July 25 for SIT probe on PM+14 Cab Ministers. Tainted team may never give us an expeditious and strong criminal justice system," she alleged, a day after she termed the PMO letter as "absolutely wishy-washy".

Later in the day, Bedi in her tweets quoted from C Rajagopalachari's Mahabharata in which Dhritarashtra is saying "I did not follow the wise path of Dharma and statesmanship but suffered myself to be misled by my foolish son. And as you say, we are fast hastening towards the abyss."

Reacting to Bedi's tweets, Khurshid said "we all felt they started off with a good idea. Idea of containing corruption and questioning corruption was a good idea. But today, they are doing greatest disservice to this idea by converting it into a personal campaign and personal ambition.

"I will quite confidently say that the country will give them a suitable answer when the time comes," he said.

The flare-up came a day after Prime Minister's Office rejected Anna Hazare's demands for setting up a SIT for probing corruption allegations against Singh and his 14 Cabinet colleagues and setting up a fast track court to take up corruption cases against MPs.

Minister of State (PMO) V Narayanaswamy yesterday alleged that Hazare was surrounded by "anti-national elements" and supported by "foreign forces".
